FUEL-HEATER.

Specification of Letters Patent.

Patented Got. 7, 1919.

Application filed May 8, 1915. Serial No. 26,839.

To all whom it may concern:

Be it known that I, HANS M. CLEMMEN- SEN, a citizen of the Urited States, residing at Houston, in the county of Houston and State of Minnesota, have invented certain new and useful Improvements in Fuel= Heaters, of which the following is a specifi cation.

This invention relates to attachments for hydrocarbon engines and the object of the same is to provide a simple and eficient device for heatingthe' fuel used by hydrocarbon engines.

Another object of this invention is to rovide a means for heating the fuel of hy ro-' to provide a heating device for fuel for hydrocarbon engines that is simple in con struction, eiiicient in operation and consists of a minimum number of parts.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is a view in elevation of an engine, and a fuel supply tank, the same being equipped with this improved heating device;

Fig. 2 is a longitudinal sectional view of that portion of the device that engages the fuel pipe and a portion of the water feeding pipes shown in elevation.

Referring to parts by reference numerals, the pipe through which the fuel passes from the su J tank to the carbureter is designated by e numeral 10 and a cylinder 11-is secured the same, preferably adjacent the carhureter. This cylinder has alined openings formed the heads 12 thereof and collars 13 are formed integrally with the heads 12 at the alined openings,

these alined openings adapted to receive the nine 10, and suitable sleeves 1a are threaded on the collars 13 so as to form an efficient liquid tight connection between the pipe 10 and the cylinder 11.

Means is provided in connection with this cylinder 11 for providing for the flow of Water through the same and thus bringing the water into contact with the fuel pipe 10. A pair of pipes 15 and 16 are connected with this cylinder 11, the same being inlet and outlet pipes respectively and cocks 17 are provided to shut of the flow of water into the cylinder when so desired. An auxiliary tributary 18 is secured to the extensions l9 and 20 on the pipes 15 and 16 respectively by means ofthe nuts 21, the same forming a by pass. A cook 22 is provided in this auxiliary tributary 18 and normally is closed. The pipe 15 as is clearly shown in Fig. 1 is in communication with the water jackets of the engine to which the device is applied and the pipe 11 is in communication with the radiator so that the water after being partially heated by passing through the water jackets of the engine is fed into the cylinder 11 by means of the pipe 15 and thus comes into contact with a portion of the pipe 10 and thereby heats the fuel contained in the pipe and as is indicated by the arrows in Fig. 2, the water flows out through the pipe 16 to the radiator for cool- 111g. most instances gasolene, not only prevents the fuel from freezing in cold weather but also provides for the fuel being fed to the carburetor in a partially heated state and thus eihciently aids in the forming of the charge. if, for any reason, it is not wished to feed the the water into the cylinder 11,

the cooks 17 can be closed and the cook 29 in the auxiliary tributary 18 opened and the Water will flow through the pipes 15, i8 and 16 to the radiator.

A drain cock 23 is provided in the cylin: der 11f0r an obvious purpose.

it is obvious that minor changes may he made in the form and construction of this invention without departing from the material parts thereofit is therefore not wished to confine the invention to the exact form herein shown and described, hut it is wished to include all such as properly some within the scope claimed.

l vhat is claimed is: in a device of the class descrihed, the conibination of a fuel suppiy pipe an engine,

an elongated cylinder having heads pro- This device by heating the fuel, in

vided with collars thereon, said supply pipe be connected to the water jacket of an engine and the remaining pipe being adapted to be connected to the radiator of such engine, an extension formed on each of the parallel pipes, said extensions being in horizontal alinement With each other, a tributary pipe having nuts on its end portions, said nuts also engaging said extensions for holding the tributary pipe upon said parallel pipes, and also parallel to said cylinder, a cock carried by said tributary pipe intermediate the ends thereof, and cocks carried by said parallel pipes at points between the extensions thereof and said cylinder, whereby the cocks may be adjusted to permit heated water to pass from the jacket of an engine, through said parallel pipes and said cylinder for heating the supply pipe, or the cooks may be adjusted for causing the water flow out around through the parallel and tributary pipes.

In testimony whereof 1 afiix my signature in presence of two Witnesses. I HANS CLEMMENSEN. Witnesses:
